This expensive blue raisin is called Qingwangqingti, which is produced in Okayama Prefecture, Japan. It is expensive because the output is low and a bunch of plants are planted. This method can give this bunch of plants the most nutrients, so the yield is low, and the daily pruning and planting techniques are also very demanding.

How to preserve raisins?

Avoid putting raisins with delicious food, because raisins will absorb the smell, which may lead to the smell of raisins.

You can cut a whole bunch of raisins into several small strings and place them. Each bunch of raisins is too dense and perishable.

It is suggested that raisins should be stored in a cool and dry environment or in a refrigerator. If damaged raisins are found, they should be taken out and stored.
